The clinical significance of PRG is related to the incidence of localized periodontitis with or without pulpal pathosis, depending on the depth, extent, and complexity of the groove. Successful treatments of PRG in singlerooted incisors have been reported in the literature. However, treatment of PRG in birooted incisors has often been ineffective. This case report describes a pulpal\u2010periodontal combined lesion occurring on a birooted maxillary left lateral incisor with concomitant PRG in a 13\u2010year\u2010old boy which was successfully treated by conventional endodontic therapy in combination with periodontal treatment including accessory root resection, radiculoplasty and bone grafting. Seven\u2010year follow\u2010up is included in this report. The basis of a successful result is accurate diagnosis and elimination of inflammatory irritants and contributory factors. Awareness of the existence of this abnormality by the clinician is important.<\/jats:italic> J Periodontol 1999;70:1540\u20101546.<\/jats:p>","DOI":"10.1902\/jop.1999.70.12.1540","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T06:03:52Z","timestamp":1107324232000},"page":"1540-1546","source":"Crossref","is-referenced-by-count":21,"title":["Successful Treatment of Pulpal\u2010Periodontal Combined Lesion in a Birooted Maxillary Lateral Incisor With Concomitant Palato\u2010Radicular Groove.
